Nexus 4 Rebooting (Stock) - Nexus 4 Q&A, Help & Troubleshooting

Hello,
I've been having a weird issue that's occurred maybe 10 - 20 times or so in the last 3 weeks. Every now and then i'll press the power button, the display will turn on, and then I can't slide to unlock or turn the display back off. After about 5 - 10 seconds the phone does a full reboot. I haven't been able to replicate the issue on any sort of consistent basis, it just happens at random.
My question is: Is there an error log somewhere that I can check? I admittedly haven't went into rooting my phone or know much about that end of it, but i'm wondering if one of the apps I have installed is causing it and figured maybe some sort of error log might help me identify the issue.
Anyone else having this problem?

N1 Turns off by itself

Hi everyone
Annoying issue. My phone is turning off (power off) randomly. Sometimes I take it out of my pocket and it is off. Then I have to reboot again with power button.
Anyone else has the same problem?
I am using CM 5.0.5.3.
Thanks
Mine reboots regularly but my phone is stock

Mine is running stock & has never ever turned off . You might have a faulty phone or problem with the rom you are using.
I had the random reboot problem on stock too, but it never stayed off.
Still happens on CM, but much less often.
Can you reproduce the problem? If so keep "adb logcat" running and see what the error is.
try pulling the last_kmsg from the phone..... Some information in there. Will at least let you know if it is hardware or software crash......
thank you martin
Little help. How do you pull that particular file?
thanks a lot
its a file, probably named so becasue it contains kernel messages (errors, debug).
Located at /proc/last_kmsg
you could pull it, tail it etc
example: tail -f /proc/last_kmsg
Yup, have the same problem sometimes
Both on stock and CM
Now I am running Modacos desire rom, and so far I don't think I have hade any unexpected reboots or shut downs
I have a similar problem but mine will sometimes turn off and not go back on for about 5 mins or so, sometimes longer, pulling the battery or even plugging it into the charger doesn't even give me the orange LED. it goes completely dead. it also sometimes gets stuck into boot mode like loop. this is on a stock N1 but this happens maybe 2-3 times per month. HTC said I can send it back or have it repaired but it's too much of a hassle and at least mine doesn't have dust under the screen if the problem persist I'll prolly send it in. BTW it's not a battery issue because I have two batteries and it's happened with both. faulty phone for sure.
I've had this happen once or twice the first couple weeks I had the phone.
It started happening to me when I installed appbrain and appaware so I uninstalled both and not done it since, so for me I think it was one of those apps!
Mine has done it once, I'm guessing it was an app that did it since one time in nearly 3 months isn't that big of a deal
I am still investigating. Its wierd that it happens morewhen I put it in the pocket. Its fine when its on the table
I have the same problem. Noticed it only happens when radio signal is very weak and a phone call comes in...Don't know if that makes any sense :S

Screen sometimes not turning off

I did it a search on here and Google, but besides one person on another forum having the same problem, I couldn't find anything. So sorry if this has been mentioned before.
The problem I am seeing is that sometimes (can't say what causes it) the screen simply won't turn off unless I do it by pressing the power button. This happened about three or four times in total and it seems unless I reboot the phone, the screen would just stay on, if I don't press the power button. I am on stock Android and the phone is not rooted and the phone is set to switch off the screen after 30 seconds.
Anyone else experienced this problem or does anyone know what the cause could be?

Could be a rogue app that's keeping your screen on, happened to me on another buggy device as well. Try using Batter Battery Stats for a while (day or 2, 3) and see if there's anything that's keeping your phone from sleeping.

[Q] Nexus 4 lastest andriod-screen turning blank

Hi,
Nexus 4 after my latest upgrade released by Android. I started facing strange problem. whenever I make anycalls my screen turns blank while call is still in progress. I couldn't disconnect from my end neither I get dialer option nor loudspeaker option. It is irritating me a lot. could you do any resolution for this. I tried factory reset as well but couldn't help it.
Hello,
I to have the very same problem. The N4 will even sometimes freeze to the point where I have reboot in order to get it working again. Frustrating though when your trying to end a call and the screen is totally blank, the waiting can vary from a few seconds to approx a minute. I'v also ran into this blank screen syndrome with using the camera, have you ran into this issue to?
Fingers crossed that someone can shed some light on this issue and possibly a fix or get around.
Thanks in advance.

Yoga 2 Pro Tablet 13 Keeps Freezing

Anyone else having a similar experience and solution ? I have done a factory reset and have barely any apps. Basically when I leave it after using it I will return and be unable to turn it on. Nothing I do seems to be able to get it going again. I place it on the charger and come back a number of hours later and eventually I can get it to restart.
Not related to battery power level, and doesn't happen all the time.
Got mine today. Happened once so far. Just hold the power button for a while and it resets.
But, this better not be a daily problem.
You still have this issue?
Disable " lock on screen " option in launcher. That option give you ability tap twice to lock screen . Regurds
It only happened to me once first day, then i got two OTA updates, and it never happened again.

Troubleshoot Random Resets?

Hello
I'm getting 1-2 restarts almost daily, and what is consistent is that the phone will short-vibrate once, then a pause of about 8 seconds, then two quick short-vibrates in succession (about .25 sec apart) and then the phone restarts.
This can happen when in my pocket, it can happen while actively using it, can also happen when just sitting there on my desk with screen on. I haven't seen a pattern regarding app use or activity triggering the restart.
I posted a question a month ago about how people with Androids can troubleshoot restarts. There HAS to be a way (app, etc) that allows you to see crashlogs **without** rooting your phone. Yet, I got no replies here to my last post.
Is this really such a hard thing to do with Android? Please, tell me if I'm wrong and missing something completely obvious. I'm right now factory resetting my phone cause I can't figure what's causing this.
Thanks in advance for the help.
I have the some.
Any once have fix for this random reboots ?
Same problem at any moment. And sometimes it stays at a boot loop.
I have changed the firmware to a custom one and the problem persist.
